The external resistance ( R ext) of microbial fuel cells (MFCs) regulates both the anode availability as an electron acceptor and the electron flux through the circuit. We evaluated the effects of R ext on MFCs using acetate or glucose. The average current densities ( I ) ranged from mA/m2 (9,800 Ω) to mA/m2 (150 Ω) for acetatefed MFCs (acetatefed reactors [ARs]), with a ...
